Purchased URL affiliated with free .coffeecup url?

I just signed on for the Webbie plan and added a url. Previously, I used the free .coffeecup address for streams. My new domain address however, still points to the old streams that were on the free .coffeecup site. For now, I changed the new url to display "Site" rather than "Streams" under settings. Questions:

1. I noticed that under Manage Domains, there was an option to point the new url away from the .coffeecup web address, to "not on s-drive." What does this do when selected?

2. Why does my free .coffeecup address still have anything to do with my newly purchased domain?

3. Is there a way to delete old streams in bundles rather than one at a time?

That is correct. We cannot rename that address, but I can delete them and then you can create a new name and point the domain to that. If that is what you would like, just open a support ticket for that and I will take care of that for you.
